proxy server and linksys router

[Gooberlx2]

I just got a linksys router (so I can connect the 7 computers in this house to the 'net on one IP) and a roomate needs to setup it up as a proxy server (socks5 or socks4) so he can use mIRC. Anyone know how to do this?

PROXIES...will not work behind the Linksys router...

To use MIRC, ports must be open (forwarded)...

I REPEAT...PROXIES WILL NOT WORK...

You can call Linksys Tech Support and they will tell you the same thing...and actully, running a proxy behind routers...will usually prevent you from even getting online....

crappy......so what do I do. sure, I can forward the port to his computer. I s'pose that's fine for now.....but I also use IRC sometimes....can I do some port triggering tricks?

 

[bbqweed]

unfortunately, the routers only allow one session to be open at a time...you might be able to forward to more than one computer, but thats not how routers were designed...

port triggering might work...so give it i try...the only thing is that with IRC...the port 113 is the ident port which lets them identify you on your connection. And, you can't really forward this 113 port to more than 1 computer...

let's just say I work with these routers on a daily basis and tried with many people to get more than 1 machine running irc simultaneously...(it doesn't seem to be happening)

***sigh*** Oh well, I rarely use IRC, and chances of us both using it at the same time are slim......I hope.

Otherwise, Is there a way I can configure one of the computers on the network to exist outside of the Router using the hardware I have? (One linksys 1-port router, 1 SMC 16-port 10/100 switch (which is behind the router)) I'm actually allowed 3 IPs by my ISP.

[edit]
Kinda OT, but.....how does IRC use IDent anyway? Does it just try to grab my host IP (i.e. 123.456.789.000) I wonder why they don't ask for host and local network IPs delimited by a ':'. Wouldn't that allow for unique identification? (i.e. 123.456.789.000:192.168.1.100) I s'pose that'd require some spankin' new function for the router....but nothing a firmware update couldn't fix......maybe.

go to the router config page...and select the advanced tab > then select the DMZ host tab...set the IP of the computer you want to be in front of the router...and all IP traffic should hit that PC....(NOTE: under DMZ....you will have NO firewall protection....)

 

[Gooberlx2]

doesn't that DMZ'ed computer still assume the same IP as the router's WAN IP?

 

[bbqweed]

well...here's an example...you would need to set the computer with a static IP address of something like:

IP: 192.168.1.10
Subnet: 255.255.255.0
Gateway: 192.168.1.1


then in the DMZ tab you enter : 192.168.1.10 --->to let the router know which computer is to be in the DMZ.

When using IRC, you give the remote user/client your WAN ip address....they make a request for data from you, the router reads the request packet and NAT realizes that there ar no ports forwarded in the "forwarding tab, but there is a computer in DMZ...so it gets routed there....

Read up on the ident rfc (or if it doesnt exist/is too boring to stay awake through, the src for an identd or something) for good information. Basically it sends an ident request to your machine, on port 113. The identd (the daemon taking the request) makes sure you are the user you say you are (the ident config thing in mIRC, on Unix-like systems its a little different).

Id recommend using servers that dont require ident.

Care to clarify this? i dont see why it wont work if setup properly...... All proxy server run behind some sort of router....

Have you 2 considered using your Room Mates Proxy Server as your router and drop the Linksys ? I *ASS*ume he is using some flavor of Linux with Squid ? All you would need is 2 network cards in the server and a switch/hub for the LAN side.
